The Precambrian–Phanerozoic and Ediacaran–Cambrian boundaries: a historical approach to a dilemma
@article{Geyer2016ThePA, title={The Precambrian–Phanerozoic and Ediacaran–Cambrian boundaries: a historical approach to a dilemma}, author={Gerd Geyer and Ed Landing}, journal={Special Publications}, year={2016}, volume={448}, pages={311 - 349} }
Abstract The Cambrian was originally defined as a rock interval with a trilobite-dominated fauna that overlay a presumed biologically barren Precambrian epoch. Work to formally define the Cambrian base arose after the discovery of Precambrian macrofossils in South Australia. The Working Group on the Precambrian–Cambrian Boundary (set up in 1972) promoted an emphasis on an extended pre-trilobitic interval with mineralized skeletal elements (small shelly fossils or early skeletal fossils). The…
